Sensitometry of Photographic Emulsions and a Survey of the characteristics of plates and films of American Manufacture
For several years the Bureau of Standards has been conducting tests and measurements of the characteristics of photographic light-sensitive materials. The ultimate object of the investigation is to standardize methods and the necessary conditions for testing these materials. At the present time workers in this field are using different standards, with the result that the data obtained are not directly comparable. It is hoped that this work will lead to the standardization that is so much needed.
